Query Available Amounts

The maximum sum of all position sizes is limited by the amount of tokens there are in the pool and any additional caps.

To calculate the available amount of liquidity for long positions:

• indexToken: the address of the token to long

• Available amount in tokens: Vault.poolAmounts(indexToken) - Vault.reservedAmounts(indexToken)

• Available amount in USD: PositionRouter.maxGlobalLongSizes(indexToken) - Vault.guaranteedUsd(indexToken)

• The available liquidity will be the lower of these two values

• PositionRouter.maxGlobalLongSizes(indexToken) can be zero, in which case there is no additional cap, and available liquidity is based only on the available amount of tokens

To calculate the available amount of liquidity for short positions:

• indexToken: the address of the token to short

• collateralToken: the address of the stablecoin token to be used as collateral

• Available amount in tokens: Vault.poolAmounts(collateralToken) - Vault.reservedAmounts(collateralToken)

• Available amount in USD: PositionRouter.maxGlobalShortSizes(indexToken) - Vault.globalShortSizes(indexToken)

• The available liquidity will be the lower of these two values

• PositionRouter.maxGlobalShortSizes(indexToken) can be zero, in which case there is no additional cap, and available liquidity is based only on the available amount of tokens
